How I migrated from HyperVM to VDSmanager

[joesdc]

I was able to successfully migrate all my hypervm nodes to VDSmanager without any data loss. Here are the steps I took.

NOTE: I was running an up to date version of CentOS 5.3 x86_64 on all my nodes. I cannot guarantee this will work for you. Be sure and make a backup before doing this.

Step 1. (Shut down HyperVM and remove it from the sytem)

# service hypervm stop
# rm -rf /usr/local/lxlabs/
# rpm -e lxphp lxzend lxlighttpd

*if your old vps configs had proper hostnames skip to step 3.

Step 2. (Fix hostname in VPS configs)

Note: HyperVM let you have VPS containers with incomplete hostnames such as "server" instead of "server.com". This will cause VDSmanager to give an error when you try to view the running VDS's. After fixing this my virtual servers started showing up on the main page list before that it just gave an error.

# cd /etc/sysconfig/vz-scripts/
# ls -l ( You should see all your VPS configs ending in .conf)

Open each one in your favorite text editor and make sure the line HOSTNAME="hostname" is a complete hostname

Example:
HOSTNAME="hostname" > WILL NOT WORK
HOSTNAME="hostname.local" > WILL WORK

Step 3. (Install VDSmanager)

# wget "http://download.ispsystem.com/install.sh"
# sh install.sh

NOTE: During the installation I chose to install the minimum. This worked for me but I cannot guarantee it will work for everyone. I have not tried installing it with the other options.

When it is done it will ask you to reboot go ahead and do so now.

Step 4. (Log into VDSmanager)

In a web browser go to this site
https://hostname-or-ip/manager/vdsmgr

Hopefully you will be able to log in and view all your running VPS containers.

After doing this on all my servers I added the old slave servers as a slave on my main VPS node and can now view all my clients from the main screen.

Good Luck

not sure what you mean about this last part

"After doing this on all my servers I added the old slave servers as a slave on my main VPS node and can now view all my clients from the main screen."

Did you install vdsmanager into a vps so that you go to the VPS url to see all the running vps across all slaves??

No I used to run use HyperVM with one master server and the rest were slaves. I'm talking about the nodes not the vm's. When I finished migrating each server (the master and the nodes) I then was able to (inside VDSmanager) add all the other servers as slaves so when I view the VDS Management page I see all the Virtual Machines for that node and the other nodes.

Quick question: Is the VDSManager requiring one license per node?

Also, can VPS's migrate back and forth from HN to HN?

Maybe it sounds like stupid questions, but I need off HyperVM too, urgently and use AWBS which supports VDSManager.

Yes. One license to node IP address. (one license per node)


Also, can VPS's migrate back and forth from HN to HN?

Yes, you can move VPS between node servers.

Prompt please. How to move client accounts hypervm whatever they can manage their servers in VDSmanager? Or are they there appearing automatically?

[slava]

Accounts of clients cannot be moved, it is necessary for you to create them anew. Only the VDS data will be automatically moved in VDSmanager to admin user.

Hi Joesdc

Thanks your step by step instructions helped me. I was facing problems and getting few errors during my installation. I could complete the installation successfully after following your steps.
